Molecules in the gas state move much faster than their liquid or solid states. Depending on the temperature and pressure, molecules can exist in three states: gas, liquid, o â¦ r solid. At high temperatures and low pressures, the gas state is favored.
I have been told that if you start using synthetic lube oil, you must continue. Going back to regular oil will damage the engine. That does not make sense to me.
To me, it's not a waste of money, so I use it. Use what you want. Just change it at least every 5000 miles to meet Toyota's requirements (unless you live in Saharan sandstorms, I can't see a reason to change more often than 5000 miles when using synthetic).
